A convenient inspection device based on shield tunnels

Abstract

This utility model relates to the field of shield tunnel inspection technology, specifically a convenient inspection device for shield tunnels. It includes a trolley with a placement box fixedly connected to its top. Both sides of the placement box are hinged to cover plates. Movable rods slide through both sides of the placement box, with one end extending into the placement box. Two sets of tension springs for moving the movable rods are installed inside the placement box. This application utilizes the method of pulling two sets of L-shaped plates towards the center of the mounting plate. The L-shaped plates move a sliding plate into the receiving hole, causing the sliding plate to separate the positioning rod from the positioning hole. This conveniently removes the restriction on the mounting plate, allowing workers to easily pull it out of the placement box for inspection. Alternatively, when the cover plate is in contact with the movable rod and the cover plate is not pressing against the movable rod, the two sets of L-shaped plates can be pulled directly, ensuring the positioning rod remains inside the moving hole, thus facilitating the removal of the mounting plate from the placement box.

Description

Technical Field

[0001] This utility model relates to the field of shield tunnel inspection technology, specifically to an inspection device for shield tunnels that is easy to inspect and maintain. Background Technology

[0002] In urban rail transit, highways, railways, and municipal pipeline projects, tunnels are located in complex underground environments for extended periods. They are susceptible to various factors such as changes in geological conditions, groundwater erosion, train vibration, and residual stress from construction. This can lead to defects such as cracks, structural deformation, leakage, and lining spalling. If these defects are not detected and addressed in a timely manner, they will gradually expand and threaten the structural safety and operational stability of the tunnel. Therefore, conducting comprehensive inspections of shield tunnels regularly is a crucial step in ensuring their long-term safe operation.

[0003] Chinese patent CN217060154U discloses a shield tunnel inspection device. By setting inserts and slots, the connecting block can be limited and fixed on the fixed block. By setting gears and racks, the two inserts can be driven to move in opposite directions, so as to be inserted into or removed from the slot at the same time. By setting worm gears and worms, it has a self-locking function to keep the inserts inserted in the slot. The device body is easy to disassemble and install.

[0004] However, the patent has the following defects in operation: when disassembling the testing equipment, it is necessary to adjust multiple transmission components such as gears, racks, and worm gears to separate the insert from the slot. Due to the lack of a mechanism that can quickly disassemble the testing equipment, the maintenance efficiency is low, which further slows down the overall testing progress and makes it difficult to meet the requirements of high efficiency in tunnel testing. Utility Model Content

[0005] This utility model aims to provide a convenient inspection device for shield tunnels, mainly to solve the technical problem that the existing technology lacks a mechanism for quickly disassembling the inspection equipment, resulting in low maintenance efficiency, further slowing down the overall inspection work progress, and making it difficult to meet the requirements of high efficiency in tunnel inspection.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A convenient inspection device for shield tunnels includes a trolley with a placement box fixedly connected to its top. Both sides of the placement box have hinged covers. Movable rods slide through both sides of the placement box, with one end extending into the placement box. Two sets of tension springs for moving the movable rods are installed inside the placement box. A guide block is fixedly connected to one end of each movable rod, and a common guide seat is fitted between the two guide blocks. A mounting plate is fixedly connected to the top of the guide seat, and an inspection device is mounted on the top of the mounting plate. Two positioning rods are slidably connected to both sides of the mounting plate, and a support spring for moving the positioning rods is installed inside the mounting plate. Two positioning holes are opened on both sides of the inner wall of the placement box. An extension plate for movement is provided on one side of each positioning rod, with the top of the extension plate penetrating the top of the mounting plate, and the outer wall of the extension plate slidingly connected to the top of the mounting plate.

[0008] The working principle and beneficial effects of this utility model:

[0009] 1. Working Principle: By flipping two cover plates on both sides of the placement box, the cover plates rotate downwards. When one side of the cover plate contacts one end of the moving rod, the cover plate presses against the moving rod. At this time, the two moving rods drive two guide blocks to press against the guide seat, which in turn drives the mounting plate to move upwards. The mounting plate then moves the testing equipment upwards. Due to the force of the support spring, one end of the positioning rod slides upwards along the inner wall of the placement box. When one end of the positioning rod slides to align with the positioning hole, it embeds into the positioning hole, thus conveniently moving the testing equipment above the placement box for testing. In addition, by pulling two sets of extension plates towards the center of the mounting plate, the L-shaped plate separates the positioning rod from the positioning hole, thus conveniently releasing the restriction on the mounting plate. This allows the operator to easily remove the mounting plate from the placement box for maintenance of the testing equipment. Alternatively, when the cover plate is in contact with the moving rod but not pressing against it, the two sets of L-shaped plates can be pulled directly, keeping the positioning rod inside the mounting plate, thus conveniently removing the mounting plate from the placement box.

[0010] 2. Beneficial effects:

[0011] (1) In the initial state, both covers are placed on the top of the placement box. At this time, due to the mutual contact of the rubber pads, the detection equipment inside the placement box is protected, so as to avoid the detection equipment being exposed to the outside all the time. Dust and debris are easy to accumulate on the detection equipment, which will affect the detection accuracy of the subsequent detection equipment.

[0012] By flipping the two cover plates on both sides of the placement box, one side of the cover plate contacts one end of the moving rod, thus pressing the moving rod with the cover plate. At this time, the two moving rods drive the two guide blocks to press the guide seat through the inclined groove, so that the guide seat moves upward along the inclined groove. At this time, the guide seat drives the testing equipment to move upward. Due to the force of the support spring, one end of the positioning rod slides upward along the inner wall of the placement box. When one end of the positioning rod slides to be aligned with the positioning hole, one end of the positioning rod is inserted into the positioning hole, thus conveniently moving the testing equipment above the placement box for easy testing.

[0013] (2) By pulling the two sets of L-shaped plates towards the center of the mounting plate, the L-shaped plates move the sliding plate into the storage hole, thereby causing the sliding plate to separate the positioning rod from the positioning hole, thus conveniently removing the restriction on the mounting plate, making it easy for the staff to pull the mounting plate out and place it inside the box, thus conveniently inspecting the equipment for maintenance work, or when the cover plate is in contact with the moving rod and the cover plate does not squeeze the moving rod, the two sets of L-shaped plates can be pulled directly, so that the positioning rod is always inside the moving hole, thus conveniently pulling the mounting plate out and placing it inside the box.

[0014] Preferably, the placement box includes a storage slot, which is located at the top of the placement box, and the outer wall of the mounting plate is adapted to the inner wall of the storage slot; so that when the mounting plate moves, it can only move up or down along the inner wall of the storage slot.

[0015] Preferably, a rubber pad is fixedly connected to one end of each of the two cover plates; the two cover plates are flipped upwards, so that the two cover plates drive the two rubber pads to rotate to the top of the placement box. At this time, due to the mutual contact and compression of the rubber pads, the testing equipment inside the placement box is protected.

[0016] Preferably, the two moving rods are staggered, and each of the two guide blocks has a sloping groove on its top. One side of each adjacent sloping groove is adapted to the bottom of the guide seat. Each set of tension springs has two springs, with one end of each adjacent spring fixedly connected to one side of the guide block and the other end fixedly connected to the inner wall of the receiving groove. Releasing the cover plate releases the pressure on the moving rods. Due to the reaction force of the tension springs, the moving rods are reset, facilitating the next use. The staggered arrangement of the two moving rods avoids mechanical interference when they move under the pressure of the cover plate, ensuring uniform pressure of the guide block on the guide seat, thereby achieving a smooth rise of the mounting plate and improving the positioning accuracy of the testing equipment.

[0017] Preferably, the mounting plate has two movable holes on each side, and the mounting plate has several storage holes that connect to the movable holes. The outer wall of the positioning rod is slidably connected to the inside of the movable holes. One end of the positioning rod is fixedly connected to a sliding plate, and the outer wall of the sliding plate is slidably connected to the inner wall of the storage holes. One end of the support spring is fixedly connected to the inner wall of the storage holes, and the other end is fixedly connected to one end of the sliding plate. When the mounting plate moves upward, the force of the support spring causes the sliding plate to move outward from the mounting plate, thereby causing the sliding plate to slide one end of the positioning rod out along the movable holes. At this time, one end of the positioning rod slides upward along the inner wall of the placement box.

[0018] Preferably, the top of the mounting plate has several movable slots that are connected to several storage holes. One end of the extension plate is fixedly connected to the outer wall of the slide plate, and the outer wall of the extension plate is slidably connected to the inner wall of the movable slot. Each of the extension plates has an L-shaped plate fixedly connected to its top. The two sets of L-shaped plates on both sides of the mounting plate are symmetrically arranged. By pulling the two sets of L-shaped plates toward the center of the mounting plate, the L-shaped plates cause the extension plates to slide inside the movable slots. At the same time, the extension plates cause the slide plate to move toward the storage holes, thereby causing the slide plate to separate the positioning rod from the positioning holes, thus conveniently removing the restriction on the mounting plate.

[0019] Preferably, both sets of positioning holes are provided on the inner wall of the storage groove, and the interior of each of the positioning holes is adapted to one end of a number of positioning rods; when one end of the positioning rod slides to align with the positioning hole, the positioning rod is inserted into the positioning hole, thereby conveniently moving the testing equipment above the placement box for easy testing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As shown, a convenient inspection device based on shield tunnel includes a trolley 1, a placement box 2 is fixedly connected to the top surface of the trolley 1, the placement box 2 includes a storage slot 4, the storage slot 4 is opened at the top of the placement box 2, and cover plates 3 are hinged to both sides of the top of the placement box 2, and rubber pads are fixedly connected to one end of each of the two cover plates 3.

[0027] Both sides of the placement box 2 are slidably connected to moving rods 5. One end of the moving rod 5 extends into the interior of the placement box 2. The interior of the placement box 2 is equipped with two sets of tension springs 18 for moving the moving rods 5. One end of the moving rod 5 is fixedly connected to a guide block 6. The two moving rods 5 are staggered. The top of the two guide blocks 6 is provided with inclined grooves 7. One side of the adjacent inclined grooves 7 is adapted to the bottom of the guide seat 8. The two guide blocks 6 are fitted with the same guide seat 8. Each set of tension springs 18 is provided with two. One end of the adjacent tension springs 18 is fixedly connected to one side of the guide block 6, and the other end is fixedly connected to the inner wall of the storage slot 4.

[0028] A mounting plate 9 is fixedly connected to the top of the guide seat 8. The outer wall of the mounting plate 9 is adapted to the inner wall of the storage groove 4. A detection device 10 is installed on the top of the mounting plate 9. The detection device 10 is a conventional tunnel wall scanner or camera in the field. In the initial state, the two cover plates 3 are flipped upward, so that the two cover plates 3 respectively drive the two rubber pads to rotate to the top of the placement box 2. At this time, due to the mutual contact and compression of the rubber pads, the detection device 10 inside the placement box 2 is protected, so as to avoid the detection device 10 being exposed to the outside. Dust and debris are easy to accumulate on the detection device 10, which will affect the detection accuracy of the subsequent detection device 10.

[0029] Two positioning rods 12 are slidably connected to both sides of the mounting plate 9. A support spring 14 for moving the positioning rods 12 is provided inside the mounting plate 9. Two moving holes 20 are opened on both sides of the mounting plate 9. Several storage holes 11 are opened inside the mounting plate 9, which are connected to several moving holes 20. The outer wall of the positioning rod 12 is slidably connected to the inside of the moving hole 20. A slide plate 13 is fixedly connected to one end of the positioning rod 12. The outer wall of the slide plate 13 is slidably connected to the inner wall of the storage hole 11. One end of the support spring 14 is fixedly connected to the inner wall of the storage hole 11, and the other end is fixedly connected to one end of the slide plate 13. Two positioning holes 19 are opened on both sides of the inner wall of the placement box 2. Both sets of positioning holes 19 are set in the inner wall of the storage groove 4. The inside of several positioning holes 19 is adapted to one end of several positioning rods 12.

[0030] By flipping the two cover plates 3 on both sides of the placement box 2, the cover plates 3 rotate downward. When one side of the cover plate 3 contacts one end of the moving rod 5, the cover plate 3 presses the moving rod 5. At this time, the two moving rods 5 respectively drive the two guide blocks 6 to press the guide seat 8 through the inclined groove 7. As a result, the guide seat 8 moves upward along the inclined groove 7, which in turn drives the mounting plate 9 to move upward. The mounting plate 9 then drives the testing device 10 to move upward. At this time, due to the force of the supporting spring 14, the sliding plate 13 moves to the outside of the mounting plate 9. As a result, the sliding plate 13 drives one end of the positioning rod 12 to slide out along the inside of the moving hole 20. At this time, one end of the positioning rod 12 slides upward along the inner wall of the placement box 2. When one end of the positioning rod 12 slides to be aligned with the positioning hole 19, one end of the positioning rod 12 is embedded in the positioning hole 19. This allows the testing device 10 to be conveniently moved above the placement box 2 for testing.

[0031] An extension plate 16 for movement is provided on one side of the positioning rod 12. The top of the extension plate 16 passes through the top of the mounting plate 9, and the outer wall of the extension plate 16 is slidably connected to the top of the mounting plate 9. The top of the mounting plate 9 has several moving slots 15 that are respectively connected to several storage holes 11. One end of the extension plate 16 is fixedly connected to the outer wall of the slide plate 13, and the outer wall of the extension plate 16 is slidably connected to the inner wall of the moving slot 15. Each of the extension plates 16 has an L-shaped plate 17 fixedly connected to its top. Two sets of L-shaped plates 17 located on both sides of the mounting plate 9 are symmetrically arranged. By pulling the two sets of L-shaped plates 17 toward the center of the mounting plate 9, the L-shaped plates 17 drive the extension plate. 16 slides inside the moving groove 15, while the extension plate 16 drives the slide plate 13 to move into the storage hole 11. Thus, the slide plate 13 drives the positioning rod 12 to separate from the positioning hole 19, thereby conveniently releasing the restriction on the mounting plate 9. This allows the staff to easily pull the mounting plate 9 out of the placement box 2 through the guide seat 8, thus facilitating the maintenance of the testing equipment 10 on the mounting plate 9. Alternatively, when the cover plate 3 is in contact with the moving rod 5 and the cover plate 3 is not pressing the moving rod 5, the two sets of L-shaped plates 17 can be pulled directly, so that the positioning rod 12 is always inside the moving hole 20, thereby conveniently pulling the mounting plate 9 out of the placement box 2.

[0032] As can be seen from the above, the specific implementation of this utility model is as follows: In the initial state, the two cover plates 3 are flipped upwards, so that the two cover plates 3 respectively drive the two rubber pads to rotate to the top of the placement box 2. At this time, due to the mutual contact and compression of the rubber pads, the detection device 10 inside the placement box 2 is protected, so as to avoid the detection device 10 being exposed to the outside all the time. Dust and debris are easy to accumulate on the detection device 10, thereby affecting the detection accuracy of the subsequent detection device 10.

[0033] By flipping the two cover plates 3 on both sides of the placement box 2, the cover plates 3 rotate downwards. When one side of the cover plate 3 contacts one end of the moving rod 5, the cover plate 3 presses against the moving rod 5. At this time, the two moving rods 5 respectively drive the two guide blocks 6 to press against the guide seat 8 through the inclined groove 7. At this time, the guide blocks 6 drive the tension spring 18 to stretch, so the guide seat 8 moves upward along the inclined groove 7. The guide seat 8 drives the mounting plate 9 to move upward, and the mounting plate 9 drives the detection device 10 to move upward. At this time, due to the force of the support spring 14, the sliding plate 13 is driven to move upward. The mounting plate 9 moves outward, causing the sliding plate 13 to drive one end of the positioning rod 12 to slide out along the inside of the moving hole 20. At this time, one end of the positioning rod 12 slides upward along the inner wall of the placement box 2. When one end of the positioning rod 12 slides to be aligned with the positioning hole 19, one end of the positioning rod 12 is inserted into the positioning hole 19, thereby conveniently moving the testing device 10 above the placement box 2 for testing. Then, the cover plate 3 is released, so that the cover plate 3 releases the pressure on the moving rod 5. Due to the reaction force of the tension spring 18, the moving rod 5 is reset, making it convenient for the next use.

[0034] In addition, by pulling the two sets of L-shaped plates 17 towards the center of the mounting plate 9, the L-shaped plates 17 cause the extension plate 16 to slide inside the moving groove 15. At the same time, the extension plate 16 causes the slide plate 13 to move into the receiving hole 11. Thus, the slide plate 13 causes the positioning rod 12 to separate from the positioning hole 19, thereby conveniently removing the restriction on the mounting plate 9. This allows the staff to easily pull the mounting plate 9 out of the placement box 2 along with the guide seat 8, thus facilitating the maintenance of the testing equipment 10 on the mounting plate 9. Alternatively, when the cover plate 3 is in contact with the moving rod 5 and the cover plate 3 is not pressing the moving rod 5, the two sets of L-shaped plates 17 can be pulled directly, so that the positioning rod 12 is always inside the moving hole 20, thereby conveniently pulling the mounting plate 9 out of the placement box 2.

[0035] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
